Abstract: 711,851. Viscosimeters. BRITISH THOMSONHOUSTON CO., Ltd. March 1, 1951 [March 22, 1950], No. 4990/51. Class 106 (2) An apparatus for determining the viscosity of fluids comprises a power driven screw threaded member 4 rotatable in a vertical open ended sleeve 1 immersed in the fluid 8 under test, the screw threads on the member 4 being such that the fluid 8 is drawn both from the top and bottom of the sleeve 1 to a central part 6 in the sleeve 1. A pressure gauge 11 connected to the central part of the sleeve 1 is calibrated to give a reading proportional to the viscosity of the fluid. A relief valve 11b may be opened sufficiently to permit a small amount of fluid flow to insure a frequent interchange of the fluid between the members 1 and 4. The pressure gauge 11 may be calibrated in a manner allowing for the flow through the valve 11b. A motor 13 and the member 4 are removable for cleaning, the sleeve 1 being removable from the fluid container for similar reasons. In a modification, Fig. 4, a transparent vertical tube 29 is rotatable about a co-axial stationary screw threaded member immersed in the liquid 34 under test. On rotating the transparent tube 29, the resulting rise of the fluid in the tube 29 is a measure of the viscosity of the fluid. The whole may be readily taken apart to facilitate cleaning.

Title: Improvements in cores for use in the manufacture of hollow objects composed of plastic material
IPC: B28B7/30
Filed: 1919-03-01
Abstract: 141,853. Mathews, C. B. March 1, 1919. Moulds.-A collapsibe core for use in casting hollow objects in concrete &c. comprises a number of curved core-plates F, G, K connected to a screw-operated draw-bar member J in such a way that when the core is to be collapsed the plates are withdrawn clear of the cavity wall one after another to leave a substantially uniform clear space all round. The bar J is mounted on a block C carried by a slipper plate or shoe H adapted to slide along the bottom of the core cavity. The bar J is thus kept in a central position in the core cavity in order that the top and bottom plates F, G may collapse uniformly. Pairs of yoke plates B connected by studs B' to the blocks C and bar J are linked by toggles A to the centre plates K. The plates F, G carry inclines D which are operated by corresponding inclines E on the bar J after the centre plates K have begun to move inwards. Pin-and-slot connexions can be used in place of inclines. The collapsing operation is effected gradually, thus allowing air to enter between the cavity wall and the core in a progressive manner and minimizing adhesive resistance. The bottom plates G are connected together by transverse plates N which pass over the slipper plate H.

Title: Salts of phosphoric acids with basic organic condensation products
IPC: C08G12/14
Filed: 1954-02-22
Abstract: Water-insoluble salts are formed from (1) a phosphoric acid having a smaller content of the elements of water than has orthophosphoric acid and (2) a condensate of an aldehyde and an acyclic compound containing at least once in its structure the unit <FORM:0786736/IV (a)/1> Suitable acids are metaphosphoric, pyrophosphoric and polyphosphoric.  The preferred aldehyde is formaldehyde and suitable nitrogen compounds are guanidine, dicyandiamide and dicyandiamidine. The condensation is preferably effected in acid medium.  Cyanamide which yields a nitrogen compound with the desired configuration may be employed.  The nitrogen compound may contain urea or thiourea. The condensate may contain alkylol groups.  The products are useful for flameproofing fibrous materials, being applied in aqueous or organic dispersion or as powders, or being formed in situ.  In the examples, dicyandiamide-formaldehyde condensates are used.  In Example 1, the metaphosphate is precipitated by addition of the corresponding acid.  (2) The pyrophosphate is similarly precipitated. (3) Sodium metaphosphate is used to precipitate the metaphosphate of the condensate.  (4) The polyphosphate is precipitated using trisodium polyphosphate.  The remaining examples are concerned with the fireproofing of textiles or the formation of fireproof boards (see Group VIII).  Example (9) uses dicyandiamide containing a little guanidine and in Example (10) the dicyandiamide is mixed with guanidine carbonate.  Specification 648,883 is referred to.

Title: Fluid mixing device
Inventor: SCHOPPE FRITZ DIPL ING
IPC: F23D14/00
Filed: 1954-02-25
Abstract: <PICT:0760610/III/1> A tubular mixing chamber 1, particularly for use as a reaction chamber or a combustion chamber for a ram-jet or turbo-jet engine, has an inlet 2 for feeding in a first fluid (e.g. combustive fluid) in such a manner that it flows helically along the wall of the chamber to the other end, a terminal rigid obstacle or end wall at the latter end to produce a substantially axial counterflow to the inlet end, creating a turbulent mixing zone between the helical flow and the counterflow, means such as a nozzle 6 to feed in a second fluid (e.g. a combustible medium) and means 3 to discharge the resultant mixture from the chamber. Reaction is improved since substantially the whole of the contents of the chamber are involved in the mixing turbulence, except for a boundary layer of fluid flowing along the wall, which protects the latter from heat of reaction or combustion and brings back towards the axis some of the heat radiated from the reaction zone; in an annular chamber, a similar boundary layer protects the inner wall.
